Let Them Come: Onslaught, from Tuatara Games, drops you onto a hostile alien world where a lone survivor must hold out for twenty minutes until extraction or a planetary nuke. The game packages that deadline into a fast-paced roguelite loop focused on movement, scavenging, and build experimentation. It pairs procedural battlefields, boss encounters, and persistent Armory upgrades with a gritty VHS aesthetic and a synth-wave score, aimed at fans of Vampire Survivors-style sessions.

What kind of game is Let Them Come: Onslaught?

This is a sci-fi survival roguelite that shifts the series from a stationary shooter to a top-down, mobile survival loop. Runs are designed around a fixed survival timer, and progression links repeated attempts through permanent upgrades and new weapon unlocks in the Armory. The sequel positions decision-making under time pressure, so each attempt asks you to balance short-term tactics with long-term build choices.

How does combat shape player choices in a run?

Combat plays as an auto-firing, positioning-first experience where you control movement while weapons discharge automatically, so spatial control matters more than precise aiming. The developer's VFX focus shows in particle-heavy explosions and screen effects that both reward aggressive play and obscure threats, forcing constant repositioning. Procedural layouts on four alien worlds change enemy placement and objectives, keeping each engagement tactically different.

What does the game look and sound like?

The presentation leans into a gritty 1980s sci-fi mood with a VHS-style visual filter and heavy particle effects for dramatic kills. The soundtrack by Cartridge 87 supplies an urgent synth-wave pulse that matches high-intensity runs. Tuatara's background in visual effects is visible in the spectacle; audio and visuals combine to create a distinct, stylized backdrop rather than a photoreal simulation.

Is it hard to get started, and what drives replay?

Onboarding emphasizes movement and positioning, so new players notice the learning curve early. Permanent Armory upgrades and multiple playable characters such as the Soldier and the Psychic provide persistent progression and varied starting strategies. Short, roughly twenty-minute sessions encourage iterative experimentation. Critics noted the initial launch content is somewhat lean, making the upgrade loop the main incentive for repeated play until additional content appears.

Clear pick for players who favour short, intense survival loops

Let Them Come: Onslaught is a compelling choice for players who enjoy high-adrenaline, decision-driven survival sessions and iterative build refinement. One consideration is the limited variety at launch noted by critics, which places greater weight on the upgrade loop. For players seeking brisk, spectacle-driven roguelite runs with strong audiovisual identity, the game suits repeated short play sessions very well.
